A plicati n fiied February 25,, 1 927. 'saai No. 170,917'.

This invention relates to a power roller for'usein connection withheaders, combines and 'other' harvesting machinery devices whereinelevator canvas' is operated. Power rollers for the purpose 'aforesaidare ofthe compostetype, metal and wood,

' to properly e levate and rotate the canvas,

whichjcarries the cut and headed grain.

Theordinary power roller for the purpose aforesaid and now in generaluse comprises a wooden body portion, *a metallc shatt and lateral crossbars or rivets engaging the shaft, andwith one`or 'both opposite ends ofthe cross bars riveted 'through the wood body and the latter isconstructed of two Sections. This 'formvof power roller is open to. a'serious objection, in that, experience shows that the constant pressureand vibration shears' or breaks off the rvets, releasng the couplingconnection between the shaft 'and wooden body 'portion and causes moreor less constant trouble, and to overcome this -troublesome feature, isthe primaryobject of the invention, and therefore theinvention has foritsobject, to provide in a manner as hereinafter set forth, a powerroller which will 'be rigid, will not be affected'by vibration, willstand the strain and stress; will materially facilitate the distributionof service when rotating and elevating the canvas'by reason of theipower thrust upon the roller,,and' further to avoid the usual' breakingand shearing of the rivets or pins now commonly'used. a

Further objects of the' invention are to provide, in a manner ashereinafter set forth, a power roller for the .purpose referred to;'which is simple in its 'construction and arrangement, strong, durable,rigid, Compact, thoroughly eflicient in its use, readily assembled andcomparatively' inexpens ve to manufacture. V l V With the foregoing. andother objects in view the invention consists' of the novel construction,combination and arrangement of parts as hereinafter more specificallydescribed and 'illustrated in the accompanying drawings, wherein is shownan embodi-j ment of the invention, but 1t is to be' under-,

stood that changes, variations and modifications can be resorted to,which fall within the scope of the claims hereunto appended.

In the drawings wherein; like reference Characters denote correspondingparts throughout the'sever'al views: V

Figure l is a fragmentary view, in elevation, of a powerf roller inaccordance with this invention. f v Figure 2 's a 'cross Sectional- Viewof a ,power roller in accordance with this invention of a'modified formand with the section taken between the transverse median and 'one end ofthe roller; I

Figure 7 is [a cross 'sectional'view, of the form of power roller shownin Figure 6' and 'taken at the tr'ansverse median of the roller.

A power roller,-in accordance-with this invention, comprises abody-portion formed of two like Sections ,1, 2 of semi-cylindrical crosssection and constructed of material other'than metal, preferably wood.The in- ,ner face of each section of the body portion of the roller isformed with a semi-'Circular groove 3 at .the longitudinal medianthereof and extending' from one end to the other end of the section. Thesection at its trans- 'verse median is formed with an opening extendingfrom the outer face of 'the section and communicating 'with the groove3. The section is furthermore provided in proX- inity to each' endthereof with a transverse opening extending from the outer face ofthesection to the tgroove v3 and the said 'openings are indicated at 5,6. Between the openngs 4 and 5 and in proximity to the opening 5, theinner face ofthe section is formed with a pair of transverselyextending, opposed spaced grooves 7, 8 and the section between theopenings 4 and' 6 and in proximi'ty to the opening 6 is formed with apair of transversely extending, opposed spacedgrooves .9, 1 0; Thegrooves 7 to 10, inclusive are formed onpthe nner face of 'the sectionand. extend'from the outer face thereof tofthe groove 3. The baseof eachof the grooves 7 to 10 inclusive, diverge in a directiontowards thegroove 3 and merge into the wall of the latter. The diverging part ofthebase of each of the grooves 7` to 10 is indicated at 11 and shown inFigure 2. The portion of each of 'the grooves 7 to 10 other than thediverging part of the V.

base thereof extends in the same plane throughout as indicated at 12.The grooves '7 to of one sectionoppose thegrooves member, carried on ashaft of the'roller and 16 of the shaft 14. The openings 4 of the whichwill be presently referred to. Each socket in cross section, is ofrectangular contour with respect to the form shown in Figures 1 to 5.The outer .end of each of the openings' 4, 5 and 6 is enlarged, asindicated at'13 Figures 2 and 3.

The metallie shaft is indicated at 14 and in cross section, conforins incontour to the opening formed by the grooves 3 when the sections 1 and 2are secured in abutting relation. As shown the shaft 1 1 is ofcylindrical cross section and is provided centrally thereof with adiametrically extending opening 15 which registers with the openings 1-of the sections 1 and 2. The shaft 14 in proxmity to each end isprovided with an opening, and which openngs are indicated at 16, 17 andalign respectively ,with the openings 5 and 6 formed in the sections oftheroll body; The shaft 141, be-

tween 'the openings 15 and 16 is provided' with a pair of integral,laterally extending and oppositely disp'osed coupling members 18, '19,and theshaft 1 1 between the openin s 15 and17 isprovided with a air ofintegral, laterally extending oppositely disposed coupling members'20,21.- Each-of said coupling members conforins in contour to theshape of asocket formed by the pair of opposed grooves 7 or 8, or 9 or 10. Thecoupling members have their positioned inwardly With respect to theperiphery ofthe body of the roller or in other words the couplingmembers are of less length than the length of the sockets, but are of asize to snugly engage the walls thereof. As the sockets are ofrectangular cross section, the coupling members are of like contour.

The' sections 1 and 2 are secured together in abutting relation, andinenveloping position with respect to the shaft 14, by clamping` members22 and each of which consists of a headed bolt provided with'a clampingnut. The bolts extend through the openings 4, 5 and 6 of the bodysection and through the openings 15, 16' and 17 of the shaft lt. Theopenings 5 of the body sections align and also align with the openingsbody Sections align and also align with the opening 15 in the shaft, andthe openings 6 of the body sections also align and align' with theopening 17. The enlarged portions at the outer ends of the openingprovide shoulders 23 and 2% and ,abutting against the shoulders 23 arethe heads of the outer ends bolts and abutting against the. shoulders24' are the' clamping nuts. The bolts are of less length than thediameter of the body portion and when the Sections of the latter aresecured in abutting relation the heads of tae bolts, as well as theclamping nuts,

are arranged inwardly with' respect to' the;

outer periphery of the body portion.

The construction illustrated in Figures 6 and 7, is the same as thatreferred to in ,connection with Figures 1 to 5, with thisx larged as at28'to provide 'shoulders 29 and against which iabutrclamping nuts "30,car

cried onthe threaded outer end 26 ofthe coupling members 25. Otherwisethan that as stated the construction shown in Figures 6 and 7, is thesame as that shown. in Figures 1 to 5 and corresponding parts are"provided with like reference characters.`

The construction of the power roller, in

accordance with thisvinvention',' provides a rigid roller that will notbe eifected byv-ibration, will stand the strain and stress, willmaterially facilitate the distribution of V service in rotating andelevating'fcanvas by reason of the power thrust upon thefroller andfurther will avoid the usual breaking and shearing of therivets or pinsnow present inthe ordinary type of power roller used, and therefore it'is thought the many advantages of 'a' power roller, in accordance wit-hthis invention, can be readily' understood, and although thepreferredvembodiment ofthe invention is as ,illustrated and described,yet it is to be understood that changes in the details ofconstructionean be had which will fall within the scope of the invention' as"claimed. r
